Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed June 8, 1998. Serial No. 437,280.

To all whom it may concern:

Be it known that I, PHILIP A. MYERS, a citizen of the United States,residing at Ashland, in the county of Ashland and State of Ohio, haveinvented certain new and useful Improvements in VVorking-Heads fol,"

Power-Pumps, of which the following is a specification, reference beinghad therein to the accompanying drawings. a

Ihis invention relates to working heads for power pumps and the objectof the invention is to provide a working head of this character whichwill permit the removal of the working parts of the pump withoutdisconnecting, or in any way interfering with the discharge pipe oroperating gearing for the pump; to so construct such a working head asto render the same water-tight at all points; to so support theoperating gearing thereon that it will not interfere with the removalof'the working parts; and to provide such a working head which will besimple in its construction and operation and which will be strong anddurable, the parts of which will notbe liable to become disarranged.

With these objects in View my invention consists in certain novelfeatures of construction and in certain parts and combinationshereinafter to be described, and then more particularly pointed out ii-the claims.

In the accompanying drawings, Figure 1 is a front elevation of a workinghead embodying my. invention; Fig. 2 is a vertical sectional view, takencentrally through the same; Fig. 3 is a transverse sectional view, takenon the line at w of Fig. 2; Fig. 4 is a sectional detail View of theupper portion of the base; Fig. 5 is a detail plan View of the base;Fig. 6 is a detail view of the cross head; and Fig. 7 is a detail viewof one of the bearing blocks.

Inthese drawings I have illustrated the preferred form of my inventionand have shown the same comprising a hollow base 1 which mav be securedupon a support or platform of any suitable character and which isprovided at a point between the upper and lower ends thereof with aninwardly extending projection or annular flange 2, upon which ismounteda supporting ring -3 adapted to support the suction pipe-4, the

ring and upper end of the suction pipe being preferably screw-threadedto enable the same to be readily connected to and disconnected saidclosure.

from each other. The flange 2and ring 3 divide the hollow base 1 intotwo parts and form above the ring 3 a chamber 5 which is provided with aclosure 6 adapted to be secured to the base by bolts 7 extending throughthe closure and through a flange 8 formed on the upper end of the base,a packing being inserted between said flange and This chamber 5 isprovided with an outlet 9 which is preferably formed integral with thebase 1 and is adapted to have the outlet pipe 10 secured thereto. Inorder that there may be no leakage between the chamber 5 and the-lowerpart of. the base, it is desirable that a water-tight oint should beformed between the flange 2 and the supporting ring 3, and, to this end,I have inserted a packing 11 between the ringand the flange and have.provided the ring with an upwardlyextending ap'ertnred collar or cage 12which, in the present instance, is formed integral therewith andterminates a short distance below the closure for the upper end of thechamber 5. Adjustable clamping members are carried by the closure 6 andare adapted to engage the upper edge of the collar 12 and thereby clampthe ring3 tightly upon theflange 2. This clamping means preferablycomprises a series of bolts 13 threaded into apertures in the closure 6and having their lower ends adapted to engage the upper edge of thecollar and their upper ends squared or otherwise provided with a wrenchgrasp 14, thus enabling the same to be turned down tightly upon thecollar 12. A suitable cap or hollow nut 15 is mounted 'upon that portionof the bolt 13 which extends beyond the closure 6, and a packing 16 isinserted between said. nut or cap and the upper side of the closure.Thus, by tightening down the cap, a water-tight connection is madebetween the cap and the closure and all leakage prevented about the bolt13, and further, the nut or cap 15 serves as a janibnut which tends toprevent the movement of the bolt 13 in theclosure 6. The pump rod 17which carries at its lower end a water liftingdiavicc, such as thepiston 18, and has connected thereto the Valve 19, extends upwardlythrough the closure 6 and is 0011- nected at its. outer end to suitableoperating, mechanism. The closure is preferably provided with a packingbox, through which the rod extends and which comprises acupsha-peddepression or gland 20 formed in the v the same in two closure 6 andhaving an aperture 21 at its lower end, through which the pump rodextends. l acking material 22 is inserted in the cup-shaped gland aboutthe rod 17 and a cap 23 is inserted in the upper end of the receptacleabout the rod 15 to secure the packing firmly in place. a

Guide rods 2% are secured to the base 1, preferably by rigidly mountingthe same in suitable apertured lugs 25 located on the opposite sides ofthe closure (5. These guide rods are adapted to engage the opposite endsof a cross head 26 which is provided with suitable guideways to receivethe same and to which the pump rod 17 is secured at a point between saidguide rods. To this end, the cross head is provided, near its oppositeends, with apertures 27 which form guideways for the guide rods 24: andnear its center with an aperture 28 within which the pump rod 17 issecured, preferably by providing the same with. an enlarged head 29 anda shoulder 30 adapted to engage the opposite edges of the cross head andprevent movement of the pump rod Within said aperture. In order that thecross head may be readily attached to and removed from the guide rod andpump rod I prefer to form pieces by dividing the same along a verticalplane, taken longitudinally of the cross head and near the center of theseveral apertures therein. This line of division extends outwardly tothe face of the cross head just beyond the apertures 27 at either end ofthe cross head and thus divides the cross head into a main portion 32and a removable portion 33 which is secured to the main portion by meansof bolts 34, and, inasmuch as the line of division extends through theapertures 27 and 28 therein, it will be apparent that upon separatingthe two partsof the cross head that the same can be entirely removedfrom the guide rods and the pump rod.

The main portion of the cross head is provided near its outer end withbearing lugs or wrist pins 35, upon which are journaled the upper endsof the connecting rods 36, the lower ends of which are journal'ed uponsuitable crank pins 37 eccentrically mounted on the gear wheels 38. aremounted upon the base 1 in any suitable manner, preferably by securingthe same to the opposite ends of a shaft 39 which is journaled insuitable-bearings 40 upon the base 1, these hearings being preferablyformed in the inner ends of brackets 41 se cured to the base near theopposite sides thereof. In order to secure these brackets firmly to thebase I prefer to provide the base with supporting plates 42, which, inthe present instance, are cast integral therewith and are of such ashape and are so arranged as, to form a supporting surface for thebrackets 41 which are detachably secured These gear wheels" thereto bymeans of bolts 43. The gears 38 are rotated by means of pinions 44mounted upon a shaft 45 which is journaled at a point removed from thebase 1 and provided with suitable driving gears, such as the pulleys 46.The shaft a5 is preferably mou nted in bearings 47 formed in the outerends of the brackets 41 and has the pinions 4-4 secured thereto on theouter sides of said bearings and the driving pulley l0 and an idler l9mounted thereon between the brackets. Thus, it will be seen that theoperating gcaring is so supported on the base 1 as to be entirely out ofalinement with the upper end thereof and that by removing the closure 6and separating the cross head from the guide rods and pump red, theentire working parts of the pump may be removed therefrom withoutinterfering with any parts thereof other than those mentioned. Theseworking parts, in the present instance, include not only the pump rodand plunger 18 and valve 19 which are connected to the pump rod, butalso the suction pipe l and the parts carried thereby, all of which may,if desired, be removed through the upper end of the base withoutinterfering either with the pipe connections or the belting or operatinggearing of the pmnp.

In pumps of this character itis very desirable that the working headshould, be what is known as a low-down head, i. 0., a head having a veryshort base and having the operating mechanism located close to thesupporting surface, thus not only economizing space and material, butbringing the strain close to the support and practically eliminating thetendency of the base to tilt and work-loose from its fastenings. It willbe observed that I have accomplished this result and have provided alow-down base having the shafts of the operating mechanism supported onone side thereof and in substantially the same horizontal plane as thechamber 5, z. 6., in a plane extending between the closure (3 andsupporting ring 3, having the operating mechanism operatively connectedto the pump rod at a point above the base. It will also be observed thatthe construction of the packing box or gland and its location relativelyto the supporting ring 3 is such as to afford a guide which willmaintain the pump rod in a position central of the suction pipe.

It will be apparent from the foregoing description that I have provideda working head of this character which will, as stated, permit theremoval of all the working parts without the dislocation of orinterference in any manner with the discharge pipe or the belts or otheroperating gearing; that thisworking head is of a water-tightconstruction, preventing all leaking between the several parts thereof;and further, that the construction and operation of the working head andits operating mechanism is of a simple character which -is not liable tobe-.

come disarranged or inoperative andwhich is of a strong, durablenaturecapable of withstanding a large amount of strain and heavy usage.

I' wish it to be understood that I do not desire to be limited to thedetails of construction shown and described, for obvious modificationswill occur to a person skilled in the art.
